FPS drops over time

[Jean Marie La Tuile]

Hello,

I play on Overthrow mod.

I use the following mods :
- ace
- CBA_A3
- Overthrow
- ACE 3 Extension (Animations and Actions)
- ACE 3 Extension (Gestures)
- Enhanced Movement
- Advanced Urban Grappling
- Advanced Towing
- Advanced Rappeling

My specs are the following :

- Ryzen 5 2600 3.4 GHz
- RX 5700 XT 8Gb DDR6
- 16 Go RAM 4133 MHz
- Installed on 1 Tb SSD

We play privately, with 4 friends maximum, using dedicated server, on Tanoa.

The problem is that when I join the server, with almost every graphic settings except maybe texture in standard or high, i get 60 fps in Small villages - 40 Fps in cities.
Then, 20 minutes later ,i get to 30 fps, no matter the place I'm in.
Then, another 20 minutes later, i get to 25 - 20 fps, no matter the place once again.


What I tried :

Into the arma 3 launcher : Cpu Count to 6 or unchecked, Memory Allocator to System or unchecked, Max Memory to 8 Gb/12 Gb or unchecked, max VRAM to 7936 Mb or unchecked.

Into Arma3.cfg : VSYNC disabled, refresh=144, MaxFramesAhead=1, DetectedFramesAhead=1.

Using autodetect for graphic settings : 30 - 20 fps right from the start.
Using Tweaks from internet (Steam guide) for graphic settings : 40 - 30 Fps, then degrading
Using almost everything on low/disabled Except Graphics settings to Standard, 60 - 40 fps, then degrading 20 minutes after playing.

I also tried setting shadows to Ultra since I saw someone say it was better, could not notice a big fps difference.

The thing is, when my fps go low after some time, it seems that no matter what I change in settings, the fps won't change at all, being stuck at 30 - 20 Fps.

Sorry for this long thread, but I would really like an answer to my problem, I be here for anymore questions.

Thank you.

I still have this issue to this day, I have no idea what causes it and it bothers me tremendously. Nothing online seems to help at all
